CONTROLLING DEYlCE FOR-LIQUlD-S-UPPLY ROLLS.

SPECIFICATION forming part of Letters Iatent No. 742,249, dated October27, 1903. Application filed February 2 7, 1 gf)h .f Serial No. 145.336.(No model.)

To all whom itdmay con/corn: v

p ing the parts in a difierent position. Be it known that I, 'WILLIAM SA KHA- VER, a citizen of the United States,'residingi at New York,county of Kings, and State of f New York, have invented certain new and{useful Improvements in Controlling Devices l for Liquid-Supply Rolls,fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

This invention relates to certain improvements in controlling devicesfor liquid-sup.

ply rolls.

In certain classes of machines itis customary to employ a liquid-supplyroll and a ductor or delivery roll which takes the liquid from thesupply-roll and delivers it. instance, in the constructions used inplanographic-printing machines, and ordinarily known as water-motions,there is employed. a fountain-roll which takes up water from a fountainand a delivery or ductor roll which takes the water from thefountain-roll and delivers it to other rolls, by which it is placed uponthe form.

The present invention has for one of its ob.- jects to produce a simple,cheap, and effective construction by which the amount of liquiddelivered by devices of the class referred to shall be controlled. V Afurther object of the invention is to produce an improved constructionby which the amount of liquid delivered by devioesof the character abovereferred to shall be controlled, which construction can. be readilyadjusted without stopping. or otherwise interfering with the Operationofthe machine.

Thus, for

With these and other objects in view the the frame.

Fig. 4 is a view similar to Fig. 2, but showing the parts in a differentadjustment. Figs. 5 and 6 illustrate a modification of the constructionshown in Figs. 1 to 4.

Referring to the drawings which illustrate one embodiment oftheinvention, 1 indicates the frame of the machine. The liquid-supplyingdevices may be of any suitable construction. Asshown,they consist of apan 2, in which rotates the usual supply-roll 3, which is journaled insuitable bearings on The delivery or ductor roll 4 may be mounted in anysuitable manner, so as to move between the supply-roll 3- and a roll 5,which is one of the rolls by which the liquid is distributed anddelivered to the form. livery or ductor roll 4 is mounted in arms 6,which are rigidly secured to a rock-shaft 7,

'journaled in suitable hearings in the frame.

The mechanism by which the rock-shaft 7 .is operated may be of anysuitable character; but as shown it includes'a suitable Operating-camand a controller, which together effeet the movements of thedelivery-roll from In the present construction the dethe supply-roll tothe distributing-roll and i which govern the time during which thedelivery-roll remains in contact with the supply-roll, andthereforedetermine the amount of liquid taken up by the delivery-roll.In the construction shown this operating-cam is a rotating cam, (marked30,) said cam being fast on and rotating with a shaft 31,,which issuitably supported in the frame of the machine.

The controller in the preferred construction comprises a block 32,which, as shown,

is pivoted at 3 3 to the cam 30, so that it may be given movementsindependent of the movement which it has when moving with the cam. Themeans for giving the controller its independent movement may be variedwidely. In thepreferred form of the construction, however, this meanswill include an adj ustable'cam 34, said cam being loosely mounted onthe shaft 31, before referred to.

The controller-block 32 is provided with a.

cam-roll 35,which cooperates with the cam 34. In the operation of thedevice the cam 34 is stationary with respect to the shaft and the cam 30and the controller-block revolve with it. The roll 35, running on thecam 34, causes the controller to be given movements the time and extentof which will depend upon the position and contour of the cam 34. Theposition of the cam 34 may be adjusted in any suitable manner. As shown,this cam is provided with ahub 36, which is surrounded by a hub 37, saidhub having a set'screw 37 tapped through it, so that the hubs 36 and 37are connected thereby. Extending from the hub 37 is an arm 38, providedwith a handle 39. By operatingthis handle the cam 34 may be adjustedaxially around the shaft 31 in any desired position. Suitable lockingmeans are provided for holding the cam in its adjusted position, andthese locking means may be of any suitable character. As shown, the arm38 carries a bolt 40, which runs in the slot 41 of a sector 42, securedto the frame. 011 the end of this bolt is a tightening-nut 43, by whichthe arm and handle may be locked in any desired position in thesectorslot.

The means by which the cam and controller operate to effect the movementof the delivery-roll may be varied and will vary according to thelocation and arrangement of the fountain.

Referring to Figs. 1 to 4, inclusive, in which the fountain is shown asabove the distributing-rolls, there is provided an operating-lever 44,which is pivoted at 45 to the frame of the machine. This lever isprovided with a bowl or roller 46, which is long enough to run both onthe surface of the cam and on the surface of the pivoted controllenblock This lever 44 in the construction shown is connected, bymeans of a link 47, to an arm 48, which is fast on the rock-shaft 7,before referred to.

The operation of the construction thus far described will be clearlyseen from the illustration in Figs. 2, 3, and 4. Referring to Fig. 2,the cam 30 and the controller-block are in such position with respect tothe cam 34 that the roll 35 is about to drop from the raised portion ofthe cam 34. In Fig. 4 the roll 35 has passed olf the raised portion ofthe cam 34, and it will be seen that the controller-block 32 has movedinward, it being guided-in its movement and the extent of the movementbeing determined in any suitable manneras, for instance, by means of apin 49, which cotiperates with a slot in the l)lockand this inwardmovement has allowed the lever 44 to descend and rock the shaft 7, thusmoving the roll 4 away from the supply-roll 3. As the cam 30 continuesto rotate the lever 44 will be allowed to rock downward still farther,so that the roll 4 will be brought into contact with thedistributingroll 5. When the. construction is adjusted as shown in Figs.2 and 3, the roll 4 will remain in contact with the roll 3 for acomparatively short time, and therefore will take up but little liquid.

If, however, it is desired to increase the time of contact between therolls 4 and 3, the arm 38 is thrown over by its handle 39, thus carryingthe cam 34 axially about the shaft 31. Such an adjusted position isshown in Fig. 4. In this figure the cam 34 is so adjusted that its highportion will act on the controller-block 35 at the time the arm 44 hasbeen raised by the high portion of the cam 30. In other words, in thisfigure after the high portion of the cam 30 has raised the arm 44 into aposition where the roll 4 is nearly in contact with the roll 3 thecontroller-block comes into operation and raises the arm 44 stillfarther, so as to bring the roll 4 into full contact with the roll 3. Atthis time the roll 35 of the controller-block hasjust begun to run onthe high concentric portion of the cam 34, and during the time when itis passing over this portion the controller-block will remain raised, sothat the roll 4 will remain for a much longer time in contact with theroll 3 than in the case of the adjustment before described, and so willtake up more liquid.

In the construction shown in Figs. 5 and 6 the fountain 2 and thesupply-roll 3 are located below the distributing-rolls 5. In this casethe operating connections are somewhat diiferent. The arm 48, whichextends from the rock-shaft 7, has connected to it a slide 51, which isguided in its movement by means of a pin 52, mounted on an arm 53,extending from the frame, said pin cooperating with a slot 54 in theslide 51. The lower end of the slide is provided with a bowl 55, whichis operated upon by the cam 30 and the controllerblock. In theconstruction illustrated in Figs. 1 to 4 the variations in the time ofcontact between the rolls 4 and 5 took place when the roll 4 wasraisedthat is to say, after it had been operated upon by the highportion of the cam 30--whereas in the present construction thevariations in the time of contact take place when the roll is lowered orafter it has been operated upon by the low portion of the cam 80. Thecam 30 is accordingly given a somewhat different shape, and thecontrollerblock instead of being moved toward the center of rotation ofthe cam 30 to interrupt the contact between the rolls 3 and 4 is movedaway from the center of rotation to accomplish the same result. Thisalso necessitates a difference in the configuration of the cam 34.

Referring toFig. .6, it will be seen that the bowl 55 has run oif thehigh portion of the cam 30, and therefore that the slide 51 has beenpermitted to drop, so that the roll 4 rests upon the roll 3. In theposition of the parts shown in Fig. 6, however, the controllerblock 32is about to run onto the high portion of the cam 34, so that thecontroller-block will be raised and will strike the bowl 55, raising theslide 51 and interrupting the contact between the rolls. If, however, itis desired to increase the time of contact between the rolls 3 and 4,the handle will be shifted, as in the construction formerly de- IFOscribed, carrying the cam 34 to the left of the observer as theconstruction appears in Fig. 6. The farther the cam is adjusted to theleft the longer it will be after the roll 55 has run off the highportion of the cam 30 before it will be struck by the controller-block,so that the longer the time will be during which the rolls 3 and 4 arein contact.

While the constructions which have been heretofore described constitutethe preferred forms of carrying the invention into effect, it will beunderstood that many changes and variations may be made therein withoutdeparting from the invention; The invention is not to be limited,therefore, to the specific constructions herein shown and described.
